Title: Base plate for lead-storage-battery electrode plate
Inventor: NAGATA YUKIHIRO
IPC: H01M4/73
Filed: 1982-03-11
Abstract: PURPOSE:To lengthen the life of a lead storage battery, and increase the performance of the battery by restricting, in a punched base plate for an electrode plate for the battery, the acute angle between a frame bone and the rolling direction of a thin plate. CONSTITUTION:The angle between the center line (mn) of a test piece 21 and a line (pq) which is parallel to the rolling direction (RD), is supposed to be theta. Various test pieces are prepared by varying the angle (theta) from 0 deg. to 90 deg., and the yield strengths of the test pieces are obtained by carrying out a tension test. As a result of such a test, it was recognized that the yield strength of the test piece almost doesn't change when the angle (theta) is varied from 0 deg. to almost 50 deg. and that it rapidly decreases when the angle (theta) exceeds 50 deg.. Therefore, the angle (theta) is restricted to within the range of 0 deg.-50 deg..

Title: Method for following-up weld line
Inventor: ISHIHARA TAKESHI
IPC: B23K9/127
Filed: 1990-02-21
Abstract: PURPOSE:To automatically follow up the weld line by reciprocating an eddy current probe perpendicularly to the weld line at the specified amplitude and bringing the center of the amplitude of the eddy current probe in line with the weld line. CONSTITUTION:The eddy current probe 1 of an eddy current flaw detector 2 is reciprocated perpendicularly to the weld line 13 at the specified amplitude. The center of the amplitude of the eddy current probe 1 is detected by a central position detecting sensor 8 via the amplitude of a holder 3 and brought in line with the weld line 13. Consequently, the follow-up to inspect the weld line can be automated.

Title: Ac motor controller
Inventor: MIZOGUCHI SHOJI
IPC: H02P23/14
Filed: 1989-02-20
Abstract: PURPOSE:To enable a stable field current control by deciding a primary side field divided current command as the feedback quantity of a magnetic flux estimated value obtained via a function generator and by controlling the deviation signal of said estimated value from a secondary side interlinking magnetic flux command to generate said primary side field divided current command. CONSTITUTION:A primary side field divided current command 12 is outputted so that a magnetic flux estimated value 39 follows a secondary side interlinking magnetic flux command 9 through a closed-loop reply decided by the gain of a flux controller 11. Therefore, even if said secondary side interlinking magnetic flux command 9 changes stepwise from zero, forcing is applied to the value of said primary side field divided current command 12 up to the output limit of said flux controller 11 and said flux estimated value 39 being the output of said function generator 38 changes gradually by the first-order lag of the primary side field divided current command 12. In this manner, because the deviation of the flux estimated value 39 from the secondary side interlinking magnetic flux command 9 becomes gradually smaller and the value of the primary side field divided current command 12 is stabilized at a normal value, it is made unnecessary to limit the rate of change of the secondary side interlinking magnetic flux command 9.

Title: Line-to-ground fault detector for high-voltage distribution line
Inventor: KOJIMA TAKAO
IPC: G01R31/08
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To detect a line-to-ground fault with high reliability by outputting a line-to-ground fault signal when the total time for which a phase difference anomaly signal is output when a specified time has passed after the detection of both a detection signal for zero-phase- sequence voltage and a detection signal for zero-phase-sequence current, exceeds a specified value. SOLUTION: The results of detection output from the zero-phase-sequence voltage level detecting circuit 4 and zero-phase-sequence current level detecting circuit 5 of the detector are input to a NAND gate 9. The inverted value of the conjunction of the two inputs is input to a specified time averaging circuit 10, and the result of comparison is also input from a zero-phase-sequence voltage/zero-phase-sequence current phase comparing circuit 6. The circuit 10 is actuated when both a zero-phase-sequence voltage and a zero-phase- sequence current are detected. Then the circuit 10 measures a time for which the value of input from the circuit 6 is '1', calculates a ratio of the measured time to a time which has passed after the stating point of the measurement, and sends the calculated value to a judging circuit 11.  The judging circuit 11 judges whether the value of output when a specified time has passed after the start of the operation of the circuit 10 is larger than a specified value. If the output value is larger than the specified value, the judging circuit 11 outputs a line-to- ground fault signal. As a result line-to-ground faults can be detected with reliability.

The light input/output element is laid out in matrix in the direction of X and Y axes, light emittng address lines X and Y are selected to make the element luminous selectively, and the photoreceiving element can be detected by photoreceiving address lines X and Y. Thus a single element is capable of emitting and detecting the light almost at the same spot, while inputting and outputting graphic forms very effectively.

Title: Electromagnetic clutch
Inventor: HAYASHI YUZO

Abstract: PURPOSE:To separate a movable iron piece from a rotor in a moment when electric conduction stops by connecting an inner rotor and outer rotor which are separately formed and form a rotor, by a connecting member made of semihard magnetic material. CONSTITUTION:When the electric conduction to a coil 7 is suspended, the excita tion for a yoke 8 is cut off, and the magnetic flux R1 stays in the yoke 8, rotor 1, and a movable iron piece 3, and the magnetic flux R1 tends to continue to attract the movable iron piece 3 to the rotor 1 side. While, a connecting member 20 continues the magnetized state, and the magnetized magnetic flux R2 is generated, and a operation of the magnetic flux R2 flows in the same direction to the staying magnetic flux R4 in the yoke 8, and the rest magnetic flux flows in the direction, i.e., inner rotor 1a movable iron piece 3 outer rotor 1b. In other words, the direction of the magnetic flux R2 is reverse to the direction of the staying magnetic flux R1 in the movable iron piece 3, and therefore the magnetized magnetic flux R2 acts so as to offset the staying magnetic flux R1. Therefore, the movable iron piece 3 can be separated from the rotor 1 in a moment, and the clutch cut-off operation can be improved.
